Hey all!

I have looked at pretty much everything (but prolly not all since I end up here :)) and am at my wits end:

I want to stream at 1080p / 60fps / medium preset. (in case someone comes with like...not all can watch at that bandwidth and such :))

This is my current single PC stream setup:

Motherboard: ASUS Rampage V Edition 10
RAM: Corsair Vengeance LPX Black 32GB DDR4-2800 CL16 quad kit
PSU: Be quiet! Dark Power Pro 11 850W
CPU cooler: ~~NZXT Kraken X62~~
(pump broke, replaced by Scythe Fuma)
CPU: Intel Core i7 6850K
GFX Card: Gainward 1080 Phoenix GLH
Case: Phanteks Enthoo Pro Window
Storage: Samsung 960 Pro 512GB (+2 HDD's +2 SATA SSD's)

(blatant copy from out of my profile:p)

And this is my new streaming PC:

CPU: AMD Ryzen Threadripper 1920X
Motherboard: Asus Prime X399-A
PSU: Be quiet! Dark Power Pro 11 850W
CPU cooler: Be quiet! Dark Rock Pro TR4
RAM: Corsair Vengeance LPX Black 16GB DDR4-3000 CL15 kit
GPU: an old ASUS 770
2 SATA SSD's for storage (close to 500 gig total, 2nd might get a Linux installation to test things...)

Capture Card: Elgato 4K60 Pro connected via HDMI from my 1080, cloned from of my ASUS ROG monitor.

in a Corsair Obsidian 750D (might replace this by a Be Quiet! Dark Base 900 rev.2 since the capture card gets HOT also ...)

Thing is, you'd expect to -easily- be able to stream 1080p/60fps at 6000kbit on the medium preset. But then I get major frame drops / high CPU load / Encoding overloaded. :(

(Plan is even to have this machine running 2 streams in the future, mine and my partners who streams Creative if possible albeit both at 720p ...)

Here is the log file:

https://obsproject.com/logs/coREFfZCN5Bh03G3
(As you can see I changed the preset during the stream going from medium to very fast eventually...)


I streamed this today on a bare and fresh install of OBS Studio with only the video capture as a source. (just to rule out anything ......)

Was mainly testing Call of Duty BO4 playing some MP with friends for a couple of hours.

That's that.

Hope someone can give me some insight / point me in the right direction....else this beautiful rig goes back to the store :\ (decision has to be made soon too :\)

Thank you for your time!

Considering my 2700X can do 1080p60 Medium on a single PC setup, I want to say this is caused by the capture card settings.

But first...

Hit Windows+i, go to Gaming. Turn off Game DVR, Game Mode, and Game Bar.

Set your Canvas and Output to 1920x1080 60 FPS
Set your Video Capture Device to 1920x1080 60 FPS

Ditch the x264 customs for now and put it on Medium

Thank you ! (again :)) I have these installed. Did not have a CD/DVD drive so ....:p (my ASUS Rampage V Edition 10 came with a USB stick!@# :)) (about time too) Will test the canvas resolution thing tomorrow. Makes sense, -but- where then does the conversion take place from 1440p to 1080p ? #curious :) (by the capture card perhaps ? Since according to Gamer Nexus it can get as hot as 90 degrees Celcius with the cover plate on......(69 without...)))

Medium on a single PC setup with an 2700X? Wow... have a similar setup as bon, just instead the 1920X I got a 1800X and can not even 1080p@60fps with fast! I know many streamers with an TR 1950X and even they cannot go above medium/slow. Is a capture card really scaling down the performance? I mean... If YOU can 1080p@60 medium with a single 2700X, then I see no need of using a streaming PC anymore. I'm quite impressed tho.

Thanks, last one I do not know yet but the game mode is off, forgot to mention that :\

17:23:29.796: Windows 10 Gaming Features:
17:23:29.796: Game DVR: On

Double check that game mode is off... it wasn't in your log.

Also, get rid of all the x.264 custom settings and try to reach the preset as it is.

I use a dual-PC setup, and in the streaming PC a 2700x has no problem at all to encode x.264 High Medium 6000kbps 1080p 60 FPS, it starts to have encoding lag in Slow preset but haven't played much with settings to see how far it can be pushed by manually tweaking. A 1920x should have power and cores enough to go to Medium with no problem I guess, but haven't tried Threadripper.

I've done both 1080p60 Medium and 720p60 Slow, both are literally on the edge in a single PC setup, I'm not saying it easy. It's not realistic to always run them

This TR is choking 30% of the frames with only a capture card, so something is not right.

Could be that they are only running dual channel ram instead of quad channel, actually it could very well be that, in some cases it halves the performance. Threadrippers need quad channel to perform their fastest, all Ryzen CPUs need fast ram but Threadrippers are 4 chips using infinity fabric hence why they work faster with quad channel.

I got 2x 8GB modules in it. Could that be it ? I did get ~2500 score on Cinebench with it though ....(but it oddly varies, but stays at the least above ~2100...)

Also the option in Ryzen Master to switch between local and distributed memory is grayed out but it does seem to switch this setting between Game Mode and Creator Mode (or what's it called, not behind my setup atm).

Will try the 1080p canvas setting first in a couple of hours and we'll see. Got about 2 days to test this still and decide if I stick with the setup. (Although a 1920X setup should -easily- be able to pull this off....and most likely also easily 2 streams say at 720p both and one being gaming and the other Creative...(less resources on the latter :p)).

The game mode was turned off after the log file btw. I thought I had it turned off but had a friend double check it with me since I do not use it and had a hard time finding it !@# :)

Quad channel ram is a must! That's your problem. You need fast quad channel ram tight timings. Like 3200Mhz CL 14 or 16 ram at least.
